This Shimano Dura-Ace cassette is manufactured from a lightweight alloy and carbon fibre reinforced polymer spider that houses 6 alloy sprockets and 5 titanium sprockets. The largest sprockets are manufactured from titanium to keep the weight low. The sprockets are also extensively cut away and drilled to further reduce weight without reducing rigidity. The very best and quickest shifts are optimised on the Shimano Dura-Ace 11 speed cassette thanks to the Hyperglide (HG) EV sprockets that have a computer designed tooth configuration with contoured shift gates.
